best way to store rubber sheet in summer weather?

[FrenchFrog33]

What is the best way to store a sheet of new rubber (still in package) during the hot, summer months?
Is refrigeration an option? Or will that crack the rubber?

Refrigeration doesn't seem like a good idea. But I don't know much about this topic.

I just keep the rubbers in ziploc bag and keep it in my room. You can also buy some airtight ziploc bags on Temu or Aliexpress where you can seal the bag and then suck out the air from the bag.

I think this would be your best bet. Seal the plastic bag and vacuum out the air.

Humidity is probably a bigger danger to the rubber due to oxidation so I'd store them sealed if possible and unsealed I'd use some silica packets to keep it dry. If you want cheap silica substitute you can store with dry rice grains.

That is an interesting idea. As far as I know, rubbers are damaged through heat, sunlight, oxidation, humidity, corrosion, and impact. The cold only makes rubber less lively, but I've never heard of rubbers being damaged from low temperatures. Normally rubbers expires 3 years after production. Perhaps refrigeration would slow down the chemical reaction from factory tuning.

So it seems air sealing your rubbers and throwing them into the fridge would extend the life of your rubbers.
